[英]How to check popup.html page when action occurs within content.js (Chrome Extension)?
My chrome extension needs to check if a checkbox is checked on the popup.html while on the page that the extension is active. 我的Chrome扩展程序需要检查扩展程序处于活动状态的页面上popup.html上是否已选中复选框。
content.js: content.js:
$(document).ready(function () {
time = setInterval(function () {
if(true){
//check if checkbox is checked??
}
}, 500);
});
popup.html: popup.html:
<!doctype html>
<html>
<head>
<input type="checkbox" name="thingToDo" value="isChecked"> Do thing<br>
</body>
</html>
Is there a way to kind of scrape the popup.html from content.js? 有没有一种方法可以从content.js中抓取popup.html? Or will I need a background.js and some sort of message sending back and forth?
还是我需要background.js和某种来回发送的消息?
You can't do a direct communication between popup.html
and content.js
, but the usual way is to use chrome.storage API. 您无法在
popup.html
和content.js
之间进行直接通信,但通常的方法是使用chrome.storage API。
Set the checked
status via popup.html
and listen for storage changes in content.js
. 通过
popup.html
设置checked
状态,并监听content.js
存储更改。
So whenever or from whereever the storage value gets changed, you will get in the content.js
因此,无论何时何地更改存储值,您都可以进入
content.js
It's the easy way and clean way too. 这也是简单方法和干净方法。
